Abstract

PURPOSE: To make possible the projection of sharp images by letting the reflected luminous flux from a photo detecting object be magnified and imaged by an objective lens.
CONSTITUTION: The photo detector 3 placed in the photo detecting window of a dark box 1 is irradiated by a light source 2. The reflected luminous flux generated from the surface of the photo detector 3 by this is magnified by a positive lens for objective and is projected onto a screen 5 or 5' depending upon whether a plane mirror 6 is used or not. This projected imaging light is formed by the reflected light without using the transmitted light of the photo detector and the projected image become sharper as compared to the case when the transmitted light is used.
